Configuration Sequence
With Cisco IOS Release 12.4(16)MR1 and later, the Cisco 3825 router supports the AIM-ATM-8 card.
Note
The Cisco 3825 router supports up to 12 ATM ports with the AIM-ATM-8 card installed in slot 0 and up
to 8 ATM ports for AIM with the AIM-ATM-8 card installed in slot 1.
The AIM for ATM card (AIM-ATM) supports up to four independent ATM links.
To determine which AIM for ATM card is installed in your router, use the show diagnostics command
in privileged EXEC mode.
To configure a Cisco 3825 router for IMA, follow these steps while in the global configuration mode:
Enter interface configuration mode and specify the location of the interface.
Step 1
Router(config)# interface atm slot /subslot/ port
Where:
slot—Specifies the slot number of the VWIC/HWIC previously assigned to the AIM for ATM
•
(Step 2
subslot—Specifies the subslot number of the VWIC/HWIC previously assigned to the AIM for ATM
•
card
port—Specifies the port on the VWIC/HWIC previously assigned to the AIM for ATM card
•
of the
For example, the following command configures the VWIC/HWIC in logical slot 0 (physical slot 0),
subslot 0, port 1 located on the motherboard of the Cisco 3825 router to be used for ATM traffic:
Router(config)# interface ATM0/2/0
Router(config-if)#
Note
Disable the IP address configuration for the physical layer interface. This and other protocol parameters
Step 2
should be configured on the IMA interface.
Router(config-if)# no ip address
Disable the Interim Local Management Interface (ILMI) keepalive parameters.
Step 3
Router(config-if)# no atm ilmi-keepalive
Specify the link that is included in an IMA group.
Step 4
Router(config-if)# ima-group group-number
Where group-number specifies the group number of the IMA group.
For example, the following command specifies the group number of the IMA group as 0:
Router(config-if)# ima-group 0
Step 5 Randomize the ATM cell payload frames.
Router(config-if)# scrambling-payload
Step 6 Perform Steps 1 to 5 to add another member link.
